To OP:
You desparately needs golden perk RSoX put i on timer. Than Decisive strikes or Pressing and Chromatic Wards (for better survival i.e. on Crom). But those 15 Prowess points you got available put to Transcendence this you need most now. And later take also Will of Sublime for more crit dmg.
Take that Spaart build which is pretty much perfect. I use exactly the same.
